Country Information

IG Factbook: "Britain's American colonies broke with the mother country in 1776 and were recognized as the new nation of the United States of America following the Treaty of Paris in 1783. During the 19th and 20th centuries, 37 new states were added to the original 13 as the nation expanded across the North American continent and acquired a number of overseas possessions. The two most traumatic experiences in the nation's history were the Civil War (1861-65), in which a northern Union of states defeated a secessionist Confederacy of 11 southern slave states, and the Great Depression of the 1930s, an economic downturn during which about a quarter of the labor force lost its jobs. Buoyed by victories in World Wars I and II and the end of the Cold War in 1991, the US remains the world's most powerful nation state. Since the end of World War II, the economy has achieved relatively steady growth, low unemployment and inflation, and rapid advances in technology."

  • As the USA is a rich country with a balanced climate, it is not required to evolve abilities such as Heat Resistance 1 and Cold Resistance 1 in order to excel in this country. Like other rich countries, the United States has a well-funded health care system, and thus it is inadvisable to start in the country, as it may take an incredibly long time to infect even a small population.  The only definite exception to this rule is if the player wants to win achievements for DarkWater when playing as the Necroa Virus. Nevertheless, it is imperative that that the player purchases Drug Resistance 1, as well as Drug Resistance 2 in Mega Brutal and Brutal difficulties.


  • If the player starts in the USA while playing the Necroa Virus, the game may say that a company named DarkWater created the Necroa Virus; a fictional American research team.
  • Despite Alaska being part of the United States, it is actually part of Canada in Plague Inc. Alaska is not part of the USA anymore, as the Canadians somehow acquired it via a treaty called the "Hay-Herbert Treaty." This was a joke put in by the game designers because an error in the game made it impossible for Alaska to be part of the USA.
    • Also, Hawaii is not seen anywhere on the map, even though it is also part of the United States. It was most likely too small for the map.
